Embodiment 1

[0069] A kind of shock-absorbing anti-bump anti-explosion low-speed tire of the present embodiment, such as figure 1 shown, including

[0070] Carcass 1;

[0071] Inner cavity 2, which is an annular cavity opened inside the carcass 1;

[0072] Also includes:

[0073] An anti-puncture cavity 3, which is a cavity opened between the tread of the carcass 1 and the inner cavity 2;

[0074] There is a thin layer between the end of the inner cavity 2 away from the anti-puncture cavity 3 and the end of the carcass 1 contacting the rim.

[0075] Tubeless tires and solid tires have large weight and high rolling resistance. When used as low-speed tires on bicycles, electric bicycles and other driving tools, it will make riding more strenuous, increase the power consumption of driving tools, and have poor elasticity and poor shock absorption effect. When the traditional inner tube tires are under-inflated, driving is laborious and power-intensive. When the tire pressure is sufficient,...

Embodiment 2

[0084] The shock-absorbing anti-bump anti-explosion low-speed tire of the present embodiment is applied to the front wheels of two-wheeled vehicles, including

[0085] Carcass 1;

[0086] Inner cavity 2, which is an annular cavity opened inside the carcass 1;

[0087] Also includes:

[0088] An anti-puncture cavity 3, which is a cavity opened between the tread of the carcass 1 and the inner cavity 2;

[0089] There is a thin layer between the end of the inner cavity 2 away from the anti-puncture cavity 3 and the end of the carcass 1 contacting the rim.

[0090] When a two-wheeled vehicle is riding, the center of gravity is concentrated on the rear wheels, which causes the front wheels to float, especially when the front wheels are traditional inner tires, the front wheels have insufficient grip, and it is difficult to control the balance of the vehicle on bumpy roads If you use solid tires or non-pneumatic tires instead, the problem of insufficient grip can be solved, but t...

Embodiment 3

[0093] The shock-absorbing anti-bump anti-explosion low-speed tire of the present embodiment is further improved on the basis of embodiment 1 or 2, such as figure 2 As shown, the distance between the end of the inner cavity 2 away from the anti-puncture cavity 3 and the end of the carcass 1 in contact with the rim is r, 1mm≤r≤5mm.

[0094] The thickness of the thin layer between the end of the inner cavity 2 and the rim should not be too thin or too thick. The cross-section of the inner cavity 2 is approximately circular. It is constantly compressed and rebounded during shock absorption, and the thin layer is prone to cracks due to stress. After the cracks appear, with the use of the tire, the cracks are easy to expand, thereby affecting the service life of the tire, and the appearance of cracks will also affect the inner chamber 2. When the thickness of the thin layer is greater than 5mm, the distance between the inner cavity 2 and the tread is too small, which weakens the a...

Abstract

The invention discloses a shock-absorbing and bumping-preventing burst-proof low-speed tire, and belongs to the field of tires. The shock-absorbing and bumping-preventing burst-proof low-speed tire comprises: a tire body; an inner cavity, which is an annular cavity formed in the tire body; an anti-pricking cavity, which is a hole cavity formed between the tire tread of the tire body and the innercavity; and a thin layer, which is reserved between the end, away from the anti-pricking cavity, of the inner cavity and the end, making contact with the rim, of the tire body. The anti-pricking cavity is formed between the tire tread of the tire body and the inner cavity, sharp objects are effectively prevented from pricking into the tire body to damage the inner tire, the burst-proof effect is achieved, the inner cavity is formed close to the end, making contact with the rim, of the tire body, and the road holding force of the tire is enhanced while the shock-absorbing and bumping-preventingperformance of the tire is guaranteed; the shock-absorbing and bumping-preventing burst-proof low-speed tire is directly formed through plastication, mold closing, injection, mold opening, secondarymold closing, gas injection, vulcanization, pressure relief, airtight layer preparation and secondary mold opening, and is easy to produce and manufacture.

Description

technical field [0001] The invention relates to the field of tires, in particular to a shock-absorbing anti-bump and anti-explosion low-speed tire. Background technique [0002] Low-speed tires are generally used for children's toy cars, bicycles, shared bicycles, electric vehicles and electric motorcycles, etc. The low-speed tires are mainly used in the following two types: [0003] a) Solid tires, that is, tubeless air-free tires. With the upsurge of shared bicycles, this kind of air-free solid tires appears in large numbers. This tire does not need to be inflated regularly, and can prevent sharp objects from piercing the carcass. A tire blowout occurs; [0004] b) Hollow tires, traditional tires with an inner cavity in the carcass. [0005] Solid tires are heavy, poor in elasticity, and high in rolling resistance. Although they save the trouble of inflating and will not blow out, they are laborious to ride, have poor shock absorption, and increase the power consumption ...
